1)About how long ago did the big bang take place?
Around 13.7 billion years ago
2)What is a black hole?
Black holes are areas of intense gravitational pressure.
3)Does the universe continue to expand?
It continues to expand and cool to this day and we are inside of it
4)Was there really a big bang?
We tend to imagine a giant explosion. Experts, however, say that there was no explosion.
5)What light elements seem to support the Big Bang Theory?
Hydrogen and Helium found in the observable universe are thought to support the Big Bang model of origins.

1) What is the current calendar most of the world uses / accepts? Explain who made it and why this is accepted. The Gregorian calendar, also known as the Western calendar, or Christian calendar. It was introduced by Pope Gregory XIII, after whom the calendar was named, by a decree signed on 24 February 1582.
2) What is a leap year? Year with 366 days: a year with an extra day, February 29, added to make up the difference between the 365-day calendar and the actual duration of the Earth's orbit of the Sun.
3) List three other types of calendars used and how they set up their calendar (ex. Lunar). Julian calendar: It is introduced by Julius Caesar, was first used in 45 BC. The calendar had 365 days in a year comprising of 12 months. Every fourth year was celebrated as a leap year with a day added to February.
Gregorian calendar: The most widely used calendar the world over, is named after Pope Gregory XIII who had sanctioned this type of calendar on February 24, 1582. Years in the calendar are numbered from the year Jesus Christ was born.
Hindu calendar: Calendar starts on Baisakhi, which falls on April 13, marking the beginning of the harvest season. There are 12 lunar months and every month begins with the occurrence of a new moon before sunrise. There are around 29 to 30 days in a lunar month as against 30 to 31 days of Solar Calendar.
4) What is BC? before Christ.
5) What is BCE? Before Common Era
6) What is AD? Anno Domini
7) What is CE? Common Era
8) What is MYA? Million years ago
9) According to the timeline site how many periods of when are there and list time.
The Big Bang: 14000 MYA Formation of Earth: 4600 MYA Cambrian: 543-490 MYA Permian: 290-248 MYA Mesozoic: 245-65 MYA Stone Age: 5 MYA – 2500 BC Ice Age: 70 000 BC – 8000 BC Neolithic: 9000 BC – 4500 BC Bronze Age: 3200-1200 BC Iron Age: 1200-332 BC Hellenistic Period: 332-63 BC Roman Period: 63BC- 476 Byzantine Period: 330 -1453 Middle Ages: 476 - 1350 Renaissance: 1350 – 1600
10) What is an eon, epoch, era, and age?
eon: longest unit of geologic time: a division of geologic time comprising two or more eras epoch: a moment in time chosen as the origin of a particular era era: a period of time made distinctive by a significant development, feature, event, or personality age: the length of time that somebody or something has existed, usually expressed in years
11) List 3 ancient calendars. Mayan calendar, Ancient Roman, Aztec calenders
12) List 2 ancient clocks and how they worked.
Sun clocks- The moving shadows formed a kind of sundial, enabling people to partition the day into morning and afternoon. Water clocks-stone vessels with sloping sides that allowed water to drip at a nearly constant rate from a small hole near the bottom.
13) What was a revolution in timekeeping? mechanical clocks
14) What allows for standard, more accurate clocks? Pendulum
15) What are time zones? A time zone is a region on Earth, more or less bounded by lines of longitude, that has a uniform, legally mandated standard time, usually referred to as the local time
16) What is the prime meridian? The zero meridian (0°), used as a reference line from which longitude east and west is measured. It passes through Greenwich, England.
17) If it is 10:00 AM in Regina, what time is it in Toronto? London? Moscow? Tokyo? Hawaii?
Toronto: 11:00 AM London: 4:00 PM Moscow: 7:00 PM Tokyo: 1:00 AM Hawaii: 6:00 AM
18) What is Daylight Saving time? Do we use this in Saskatchewan?During late winter we move our clocks one hour ahead and lose an hour during the night and each fall we move our clocks back one hour and gain an extra hour. We use this in Saskatchewan.
19) Is there a year zero? Year zero does not exist in the Gregorian calendar or in the Julian calendar. Under those systems, the year 1 BC is followed by AD 1. However, there is a year zero in astronomical year numbering (where it coincides with the Julian year 1 BC).
20) Are we starting a new decade in 2010 or 2011? 2011
21) What is linear time? Linear time is a concept where by time is seen sequentially, as a series of events that are leading toward something: beginning, and an end.
22) What is cyclical time? Time that flows in a cycle; seasons, day and night, etc.
